Gulfstream G600 vs Gulfstream G500 vs Gulfstream G400

The Gulfstream G600, G500, and G400 are all large-cabin business jets, but they step down in capability from longest-range to shortest-range. The G600 sits at the top of this group as an ultra-long-range, large-cabin jet designed for the longest intercontinental missions, offering about 6,600 nautical miles of range and typically seating around 13 to 19 passengers depending on configuration. The G500 is a long-range, large-cabin jet positioned below the G600, with roughly 5,300 nautical miles of range and a similar typical capacity of about 13 to 19 passengers, though it’s more often optimized for slightly shorter missions than the G600. The G400 is the newest and smallest of the three in capability, aimed at the large-cabin, long-range segment but with a shorter reach than the G500, at about 4,200 nautical miles, and a typical capacity around 12 passengers in standard layouts, with maximum seating varying by configuration. Overall, passenger counts overlap, but range and mission profile clearly differentiate them.
